Fröruper Hills Nature Reserve

Highlight • Natural Monument

The Frörup Mountains have a wide range of changing natural areas.
Here you can find the rewetted Budschi Moor, dry heath areas on its edge, terminal moraine hills lined with beech and oak trees, the Ihlsee stream lowlands, the Treßsee lowlands and the areas along the Treene with the Treenetal.
This beautiful landscape was created during the Vistula Ice Age around 12,000 years ago, in which the glaciers pushed up large amounts of material to form the so-called "compressive moraines". The “trademark” of the Frörup mountains are the wooded moraine hilltops. Here you feel like you have been transported to a low mountain range. Sometimes it goes up and down quite a bit.
The Budschi Moor was used for peat extraction for a long time, but is now waterlogged again and can now develop into a moorland undisturbed. Here on Budschi Moor, a former stone cellar of a residential building was converted into a bat roost. The former Jordhui Moor is now a wide area of heath. The areas are kept open by a herd of migratory sheep so that they do not become overgrown.
The enormous importance of this landscape, which is worthy of protection, is underlined by the EU's designation of large areas as fauna-flora-habitat areas (FFH), and since 2015 an area of 1,674 hectares has been designated as one of the largest NSGes in the country. The NSG is looked after by the Obere Treene Landschaft nature conservation association. A variety of plant, fungi and animal species are native here, including the rare, endangered pasqueflower, various species of orchids, sand lizards and black woodpeckers.
Because of its varied landscape in a small area, this area also has great recreational value and is therefore very popular.

Hechtmoor Nature Reserve

Highlight (Segment) • Natural Monument

The pike bog is a small raised bog typical of the fishing moraine landscape. It was created after the last ice age and is gallery-like surrounded by an alder forest. In the core zone of the bog, significant stocks of the raised bog plant society grow with bell heather, rosemary heather, cranberry and deciduous cotton grass. In places, these stocks are lined with fragrant shrubbery. With its striking yellow flowers, the moor lily is considered a character plant of the pike bog. The heavily endangered sundew is also common.

Gradually silting peat stitches contain unusually diverse peat moss grass. The diverse flora of the pike bog enables a species-rich insect life. Dragonflies with many different species are particularly represented.

It's definitely worth visiting at any time of year. In winter, you should wear sturdy shoes to get through some wet areas.

The "Robbers' Cave" is located in the Idstedt Forest south of the town of Idstedt. Coming from Schleswig, it is located 150 meters behind the "Wilhelmslust" junction on the right-hand side of the road. The Idstedt Robbers' Cave is one of the few passage graves in Schleswig-Holstein that is still in good condition. It consists of a chamber and a structurally separated passage. The Neolithic megalithic structure dates from the Funnel Beaker culture and was built between 3,500 and 2,800 BC. To this day, it has not been proven whether robbers ever stayed inside the cave.

Sankelmarker Lake is a natural body of water from the last ice age, which is now fed by two streams and various springs on the banks and bottom. This constant supply of fresh water has ensured the excellent water quality of the relatively deep, clear lake in recent years. Ideal conditions for fishing at Sankelmarker Lake. Due to the extreme nutrient input from the surrounding agriculture, however, there is an increasingly explosive proliferation of phytoplankton in the summer months, which pollutes the water. It is then also not possible to swim at Sankelmarker Lake. The banks are largely covered with trees and very difficult to reach. There are jetties, but almost all of them belong to private property. There are a few free bays on the south bank. A boat can be launched here. Fishing at Sankelmarker Lake from a boat

A small tour takes you around Lake Sankelmark. Hiking tour "Water experience": The hiker is guided over 4.2 km for around 90 minutes, always directly on the water. Enjoy the special atmosphere of the lake and listen to the sound of the small waves. Seabirds can be observed with the observation telescope. The academy center is also worth a visit.

The name “Idstedt Robbers’ Cave” seems misleading at first – after all, the place is not a cave or a real hideout for robbers, but a Neolithic megalithic tomb, a so-called dolmen.
